Retain what works, assess what does not
If the door has fittings or finishes you want to preserve, mention them before choosing a replacement. The dimensions, condition and existing lock arrangement affect what is compatible. Appearance is one consideration; the lock must also operate properly with the door and frame. An exact match or a particular product should not be assumed before the hardware is assessed.
Understand the proposed improvement
British Standard lock options and anti-snap euro cylinders can be discussed where suitable. They are not interchangeable solutions for every door. Ask which component would change and why it fits your entrance. If the door is already difficult to close or lock, that fault needs considering alongside an upgrade, rather than treating new hardware as an automatic cure.
Separate a security review from an urgent failure
A planned review allows time to discuss priorities and access arrangements. If you are locked out or the entrance will not secure, say that first when calling 020 3519 9290. PrimeKey London offers 24/7 emergency support, with non-destructive entry preferred where possible. The proposed work and quote are explained before the job begins, whether repair or replacement is appropriate.
Choose the help you need
Before you call
Have your postcode ready and explain whether the door opens, whether the key turns and whether you can secure the property. For shared buildings, tell us about concierge arrangements. An adult authorised to request the work should be available.
